Abstract
Devices and methods for indicating power on a torch. In one example, a welding or plasma cutting torch includes an indicator coupled to the torch. The torch also includes control circuitry coupled to the indicator and configured to provide a first signal and a second signal to the indicator. The indicator is configured to receive the first signal when at least one of welding power and arc starting power from a power supply is available at the torch and to receive the second signal when the at least one of active welding power and the arc starting power from the power supply is not available at the torch.
Claims20
A welding or plasma cutting torch, comprising:
- an indicator coupled to a body of the torch;
- and
- control circuitry coupled to the indicator and configured to provide a first signal and a second signal to the indicator;
- wherein the indicator is configured to receive the first signal when at least one of welding power and arc starting power from a power supply is available at the torch, the indicator is configured to receive the second signal when the at least one of the welding power and the arc starting power from the power supply is not available at the torch, the first signal comprises a voltage signal while welding or cutting is not occurring, and the first signal comprises a current signal while welding or cutting is occurring.
A method for indicating that a welding torch is receiving at least one of active welding power and arc starting power from a welding power supply, comprising:
- receiving a first signal at the welding torch while the welding torch is receiving the at least one of the active welding power and the arc starting power;
- providing a first indication that the welding torch is receiving the at least one of the active welding power and the arc starting power based at least partly on the first signal;
- receiving a second signal at the welding torch while the welding torch is not receiving the at least one of the active welding power and the arc starting power;
- and
- providing a second indication that the welding torch is not receiving the at least one of the active welding power and the arc starting power based at least partly on the second signal.
A welding or plasma cutting torch comprising:
- an indicator configured to indicate when at least one of welding power and arc starting power is available at the torch;
- and
- a battery configured to power the indicator.
